Kev paub txog kev lag luam tooj liab: txhua yam khoom ntawm tooj dag raj
Brass tube: Ib hom tsis-ferrous hlau raj, uas yog nias thiab kos seamless raj. Cov raj tooj liab muaj zog thiab corrosion-resistant, thiab tau dhau los ua thawj qhov kev xaiv rau cov neeg cog lus niaj hnub los txhim kho cov kav dej, cua sov thiab cua txias kav hauv txhua lub tsev lag luam. Cov kav dej tooj dag yog cov kav dej zoo tshaj plaws.

Cov yam ntxwv ntawm tooj dag tubes:
Cov raj tooj dag yog lub teeb hauv qhov hnyav, muaj cov thermal conductivity zoo, thiab lub zog kub qis. Lawv feem ntau siv los tsim cov khoom siv hluav taws xob sib pauv (xws li condensers, thiab lwm yam). Lawv kuj tau siv los sib sau cov kav dej kub qis hauv cov khoom siv oxygen. Cov raj tooj liab uas muaj cov kab me me feem ntau yog siv los thauj cov kua uas muaj zog (xws li lub tshuab lubrication, roj siab tshuab, thiab lwm yam) thiab ua cov ntsuas siab rau cov twj paj nruag. Brass tubes muaj zog thiab corrosion-resistant.
Nws muaj cov txiaj ntsig tseem ceeb hauv qab no: Cov raj tooj liab yog qhov nyuaj, tsis yooj yim rau corrode, thiab tiv taus qhov kub thiab txias. Lawv tuaj yeem siv rau hauv ntau qhov chaw uas tsis yog tooj liab. Piv nrog rau cov kav dej tooj dag, ntau lwm cov kav dej muaj qhov tsis zoo. Piv txwv li, galvanized steel kav, uas tau siv ntau zaus hauv cov tsev nyob yav dhau los, yooj yim heev rau xeb. Tom qab siv sijhawm luv luv, cov teeb meem xws li yellowing ntawm kais dej thiab txo cov dej ntws yuav tshwm sim. Qee cov ntaub ntawv yuav txo tau lawv lub zog sai ntawm qhov kub thiab txias, uas yuav ua rau muaj kev phom sij tsis zoo thaum siv hauv cov kav dej kub. Txawm li cas los xij, vim qhov kub ntawm qhov kub ntawm tooj liab, uas yog siab li 1083 degrees, qhov kub ntawm cov dej kub yuav muaj kev cuam tshuam me ntsis ntawm cov kav dej tooj dag. Cov kav dej tooj dag muaj xws li cov kav dej tooj dag rau cov khoom siv hluav taws xob, cov kav dej tooj dag rau cov tub yees, cov kav dej tooj dag siab, cov kav hlau tsis muaj zog, cov kav dej tooj dag rau kev sib txuas, cov kav dej tooj dag rau cov kav dej, cov kav hluav taws xob cua sov tooj dag, thiab cov kav dej tooj dag rau kev lag luam.

Kev ceev faj rau tooj dag tube welding:
1. Thaum lub sij hawm vuam, nco ntsoov khaws cov nplaim taws npog qhov sib koom ua ke kom tsis txhob muaj cua nkag mus;
2. Lub flux yuav qhuav tawm, dej yuav evaporate ntawm 100 degree, thiab flux yuav tig milky dawb;
3. Lub flux yuav npuas ntawm 316 degree;
4. Lub flux yuav muab tshuaj txhuam ntawm 427 degree;
5. Lub flux yuav dhau los ua kua dej ntawm 593 degree, ze rau qhov kub ntawm cov tooj liab vuam;
6. Solder muaj 35% -40% nyiaj yuav yaj ntawm 604 degree thiab ntws ntawm 618 degree;
7. Ua tib zoo saib ob lub workpieces raug welded Txhua qhov yuav tsum tau ua kom sov nrog lub vuam vuam;
8. Cov xim ntawm cov nplaim hluav taws tuaj yeem siv los soj ntsuam seb qhov ntsuas kub puas tsim nyog. Thaum qhov kub nce mus txog qhov kub ntawm cov tooj liab vuam, cov nplaim yuav tshwm ntsuab, thiab thaum nws ncav cuag qhov kub ntawm qhov kub, cov nplaim ntsuab qhia tias qhov kub thiab txias yog qhov tsim nyog;
9. Thaum vuam cov kav dej tooj liab thiab cov kav hlau hlau rau ib leeg, cov yeeb nkab tooj liab yuav tsum tau ua kom sov ua ntej (vim tias cov yeeb nkab tooj liab ua kom sov sai thiab xav tau cua sov ntau dua);
10. Thaum lub sij hawm cov txheej txheem vuam tooj liab, lub vuam teeb yuav tsum tsis txhob nres ntawm ib qho chaw, tab sis tuaj yeem txav mus rau hauv ib qho 8- zoo li tus;
11. Nws raug nquahu kom siv lub teeb vuam loj, kom cov nplaim taws tuaj yeem siv tau kom tau txais cov cua kub tsis dhau los yog "tshuab". Nws yog qhov zoo tshaj kom muaj me ntsis plaub ci ntawm cov nplaim hluav taws hauv conical.
